下面示例中，当姓名所在td的宽度是60px，如果第二行里的文字较少时，显示正常，如果第二行里的文字较多时，则显示不正常了

<body>
<table width="200" cellspacing="0" cellpadding="0">
<tr>
<td width="60">姓名：</td>
<td>某某</td>
</tr>
<tr>
<td colspan="2">个人简介</td>
</tr>
</table>
<table width="200" cellspacing="0" cellpadding="0">
<tr>
<td width="60">姓名：</td>
<td>某某</td>
</tr>
<tr>
<td colspan="2">个人简介个人简介个人简介</td>
</tr>
</table>
</body>
</html>
解决方法一：（对第二列td也设置宽度）
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>查字典教程网</title>
<style type="text/css">
.mTable{width:200px;border:1px solid #666;border-collapse:collapse}
.mTable td{border:1px solid #666}
</style>
</head>
<body>
<table width="200" cellspacing="0" cellpadding="0">

<td width="60">姓名：</td>
<td width="140">某某</td>

<table width="200" cellspacing="0" cellpadding="0">
<tr>
<td width="60">姓名：</td>
<td width="140">某某</td>
</tr>
<tr>
<td colspan="2">个人简介个人简介个人简介</td>
</tr>
</table>
</body>
</html>
解决方法二：（设置table-layout:fixed）
<!DOCTYPE HTML>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>查字典教程网</title>
<style type="text/css">
.mTable{width:200px;border:1px solid #666;border-collapse:collapse;table-layout:fixed}
.mTable td{border:1px solid #666}
</style>
</head>
<body>
<table width="200" cellspacing="0" cellpadding="0">
<tr>
<td width="60">姓名：</td>
<td>某某</td>
</tr>
<tr>
<td colspan="2">个人简介</td>
</tr>
</table>
<table width="200" cellspacing="0" cellpadding="0">
